Rectangular framed structures
Framed Structures
• There are two different types of framed
structures used for building:
Rectangular frames
Rectangular Framed
Structures
A framed structure is a network
of beams and columns joined
up to form the skeleton
framework of the building.
The structural frame carries the
total load of the building and
transfers it to the foundation.
Cladding is fixed over the
framework, or infill panels are
placed between its members, to
totally enclose the space within
the building.
 Framed structures are easily erected from premade members.
 These members are easily connected together
in the correct sequence to form the structural
framework.
 Problems arise when large members are used
and when the height of the structure makes
lifting difficult.
 In these situations a crane will be needed to lift
the members into place.
 Rectangular frames are usually made from
steel but they may also be made from concrete.

Rectangular framed structures are
used for multi-storey buildings
such as:
Office Blocks
Large Schools
Hotels
Hospitals
or other similar buildings where a
multi-storey structure is required.
The floor space will incorporate a
large number of columns.

•Rectangular framed
structures are a series of
upright and horizontal
members.
•They are set a right angles
to each other to provide
support for the floors, walls
and roof.
•The uprights are called
columns.
•The horizontal members
are called beams.
Structural stability of a
rectangular framed
structure.
Increased structural stability is
achieved by adding of lift
shafts, stair cases and the
rigidity achieved by the
external cladding..
